Description

Technical Field

[0001] This invention belongs to the field of aerospace manufacturing technology, specifically relating to a method and apparatus for manufacturing a high-height hyperboloid wedge-shaped honeycomb core. Background Technology

[0002] Metal honeycomb sandwich structures, composed of upper and lower panels and a central honeycomb core, possess excellent load-bearing and functional characteristics, including light weight, high specific strength and stiffness, high temperature resistance, and impact resistance. Used as a fuselage panel structure for an aircraft, compared to stiffened panel structures, it reduces mechanical connections, effectively decreasing the number of structural parts, reducing weight, and improving efficiency. Furthermore, the absence of mechanical connection pin holes effectively reduces fatigue sources. In particular, under high temperatures, the metal honeycomb structure, being an integral structure, exhibits more uniform load-bearing and deformation processes.

[0003] Based on the design requirements of a certain aircraft fuselage panel structure, a high-height hyperboloid wedge-shaped honeycomb structure needs to be manufactured, with the following cross-sectional dimensions: Figure 1 As shown, the height of the hyperboloid wedge-shaped honeycomb core ranges from 6mm to 87mm, the length is approximately 610mm (L direction), the width is approximately 600mm, and the size of the honeycomb core cell is 11.2mm.

[0004] The current manufacturing method of this honeycomb core is as follows: First, a forming method is used to manufacture the honeycomb core corrugated strip. A 100mm high foil strip is extruded into a corrugated strip through two forming wheels. The length of the corrugated strip is 650mm. Then, the corrugated strips are resistively spot-welded to form a cuboid honeycomb core with a length of about 650mm (L direction) and a width of about 640mm. Then, the honeycomb core is machined by first holding and then machining to obtain a high-height hyperboloid wedge-shaped honeycomb core.

[0005] The direct-fixation machining method for manufacturing rectangular honeycomb cells has the following problems and disadvantages:

[0006] 1. Low production efficiency and long manufacturing cycle. Currently, manual resistance spot welding is used to assemble large-height honeycomb cores, and the larger the size of the honeycomb core, the longer the welding time required.

[0007] 2. Low material utilization and high manufacturing cost. The final processed honeycomb core volume is about 1 / 3 of the volume of the cuboid honeycomb core. The method of first welding the corrugated strips into a 650mm x 640mm cuboid honeycomb core and then performing the holding machine processing will waste 2 / 3 of the honeycomb core. The honeycomb foil strip is very expensive, the material utilization is low, and the manufacturing cost of the honeycomb core is very high.

[0008] 3. Poor machining accuracy. Large-sized honeycomb cores exhibit significant welding deformation. After machining, stress release leads to severe surface distortion, making it difficult to guarantee machining accuracy.

[0009] To address the above issues, we consider a method that involves first welding a rectangular honeycomb core with half the original volume, then dividing this honeycomb core into two trapezoidal honeycomb cores, and finally welding them together to form a wedge-shaped honeycomb core of suitable size for holding and machining. This method saves a significant amount of honeycomb foil strip and welding time, shortens the manufacturing cycle, and reduces manufacturing costs.

[0010] However, the method of segmenting and welding rectangular honeycomb cores presents the following technical challenges:

[0011] 1. Due to the large step size of the high-height honeycomb core during the welding process, it is easy to miss the material after cutting it with wire cutting. It is understandable that the cut surface may not be precise enough and may not fully achieve the expected shape, forming a defect similar to a "pit", which will affect the subsequent welding.

[0012] 2. The honeycomb core is weakly rigid, and large-sized and high-height honeycomb cores have high internal stress. During wire cutting, as the cutting depth increases, the internal stress of the honeycomb core is released, and the core is prone to deformation, which can lead to wire breakage or deformation at the theoretical cutting position.

[0013] 3. After cutting, when welding the two trapezoidal honeycomb cores, it is difficult to guarantee the splicing accuracy due to the deformation and step difference between the two cores. Summary of the Invention

[0014] (a) Technical problems to be solved

[0015] This invention addresses the above-mentioned problems by proposing a method and apparatus for manufacturing high-height hyperboloid wedge-shaped honeycomb cores. Its purpose is to solve the shortcomings of the direct holding and machining method for cuboid honeycomb, including low production efficiency, long manufacturing cycle, low material utilization, high manufacturing cost, and deformation and poor precision during processing.

[0016] (II) Technical Solution

[0017] To achieve the above objectives, the first aspect of the present invention provides a method for manufacturing a high-height hyperboloid wedge-shaped honeycomb core, comprising the following steps:

[0018] Corrugated strip materials are welded together to form a cuboid honeycomb core, the cuboid honeycomb core having a predetermined size;

[0019] Use the left and right side plates with positioning grooves to position and fix the cuboid honeycomb core;

[0020] The rectangular honeycomb core is divided into two trapezoidal honeycomb cores of the same size using wire cutting technology.

[0021] The segmented trapezoidal honeycomb core is positioned using the support strips on the base plate. The two positioned trapezoidal honeycomb cores are then clamped between the base plate and the inclined cover plate and secured with screws.

[0022] Use a graduated hook resistance spot welding gun to spot weld two trapezoidal honeycomb cores together to form a whole wedge-shaped honeycomb core.

[0023] The formed wedge-shaped honeycomb core is subjected to holding machine processing to obtain a high-height hyperboloid wedge-shaped honeycomb core of the target size.

[0024] Furthermore, both the left and right side plates have evenly distributed round holes. The trapezoidal honeycomb core is spot-welded to the round holes distributed on the left and right side plates using straps to position the trapezoidal honeycomb core.

[0025] Furthermore, the cuboid honeycomb core has a height of 136mm, a length of 650mm, and a width of 320mm, wherein the length direction refers to the direction of the corrugated strip.

[0026] Furthermore, during the wire cutting process, the long side and end of the right side plate are used as the machining reference for wire cutting.

[0027] To achieve the above objectives, a second aspect of the present invention provides an apparatus for manufacturing a high-height hyperboloid wedge-shaped honeycomb core, comprising:

[0028] The positioning side plate includes a left side plate and a right side plate. Both the left side plate and the right side plate are provided with positioning grooves and round holes for positioning and fixing the cuboid honeycomb core and reducing the deformation of the honeycomb core. The positioning grooves are provided on the opposite clamping surfaces of the left side plate and the right side plate.

[0029] Wire cutting equipment is used to divide a rectangular honeycomb core into two trapezoidal honeycomb cores;

[0030] A welding fixture includes a slanted cover plate, a base plate, and screws. The base plate has multiple rows of support bars symmetrically arranged in the middle so that part of the honeycomb cells of two trapezoidal honeycomb cores are embedded in the support bars. There are two sets of slanted cover plates, which clamp the trapezoidal honeycomb cores embedded in the support bars between the slanted cover plates and the base plate through the screws. A gap is left between the two sets of slanted cover plates, and the gap is located above the position of the two trapezoidal honeycomb cores to be welded.

[0031] The welding equipment is equipped with a hook resistance spot welding gun, which is used to extend into the gap to perform spot welding of two trapezoidal honeycomb cores.

[0032] Furthermore, the hook resistance spot welding gun has a graduation mark.

[0033] Furthermore, the support bar is in the shape of a hexagonal prism.

[0034] Furthermore, the height of each of the aforementioned support bars is not higher than the height of the corresponding honeycomb lattice of the embedded trapezoidal honeycomb core.

[0035] Furthermore, the number of the circular holes is multiple sets, evenly distributed along the plate surface where the positioning groove is located.

[0036] (III) Beneficial Effects

[0037] Compared with existing technologies, this invention provides a method for manufacturing a high-height hyperboloid wedge-shaped honeycomb core. First, a cuboid honeycomb core is divided into two trapezoidal honeycomb cores using wire cutting equipment. Then, these trapezoidal cores are welded together using welding fixtures to form wedge-shaped honeycomb cores of suitable dimensions. Finally, the hyperboloid wedge-shaped honeycomb core is manufactured using a holding machine. This reduces material waste and welding time, effectively improving production efficiency and lowering costs. During processing, side plates with positioning grooves are used to fix the trapezoidal honeycomb cores, reducing wire cutting accuracy issues caused by deformation due to loosening and stress release during cutting. Fixing and precise positioning maintain the shape of the trapezoidal honeycomb core. The method of using a base plate support and inclined cover plates and screws to press the trapezoidal honeycomb core improves the accuracy and stability of the welding process, reducing step differences and flatness differences caused by deformation. Finally, a resistance spot welding gun with hooks and support bars are used to position and control the weld points, ensuring uniform distribution and strength, thereby improving the quality and performance of the final product.

[0046] The present invention will now be described in detail with reference to the accompanying drawings, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] When performing wire cutting of high-height honeycomb cores, stress is generated during the welding process, causing varying degrees of twisting and deformation of the honeycomb cores, making it difficult to determine the wire cutting position. At the same time, as the cutting depth increases during the wire cutting process, the internal stress of the honeycomb core is released, and the core is prone to deformation, leading to wire breakage or deformation at the theoretical cutting position.

[0050] To address this problem, this invention proposes a method for manufacturing a high-height hyperboloid wedge-shaped honeycomb core. This method involves designing appropriate clamping fixtures to reduce deformation of the honeycomb core and ensure accurate positioning. The honeycomb core is fixed using two side plates with positioning grooves, achieving positioning in both the length and thickness directions. Due to the torsional deformation of the honeycomb core, circular holes are designed on the two side plates. The honeycomb core and the distributed circular holes on the side plates are spot-welded together with straps to achieve positioning in the height direction. Finally, wire cutting is performed using the long side and end of the right side plate as the machining reference to achieve wire cutting machining of the honeycomb core.

[0051] When welding two trapezoidal honeycomb cores, direct welding due to the twisted deformation of the honeycomb cores can cause problems such as step differences and uneven flatness. Resistance spot welding from inside the core cell cannot guarantee the uniformity of weld point distribution and weld strength. To address this, a method using a slanted cover plate, a base plate, and screw clamping is employed to reduce the deformation of the two trapezoidal honeycomb cores and minimize step differences. The honeycomb core cells are positioned using hexagonal prism support strips on the fixture base plate, and welding is performed using a graduated hook resistance spot welding gun to ensure uniform weld point distribution and weld strength.

[0052] The various non-limiting embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0053] A method for manufacturing a high-height hyperboloid wedge-shaped honeycomb core according to an embodiment of the present invention may include, for example, the following steps:

[0054] S100. The corrugated tape material is welded together to form a rectangular honeycomb core. The rectangular honeycomb core has a predetermined size, as shown in the appendix. Figure 2 .

[0055] First, a honeycomb core corrugated strip is manufactured using a molding method. Then, the corrugated strip is welded together to form a rectangular honeycomb core 1 with a height of 136mm, a length of 650mm (L-direction), and a width of 320mm. Figure 2 As shown, L-direction refers to the direction of the honeycomb corrugated strip.

[0056] S200. Use the left and right side plates with positioning grooves to position and fix the cuboid honeycomb core.

[0057] Then, wire cutting is performed on the cuboid honeycomb core 1, and the cuboid honeycomb core 1 is cut as follows: Figure 3 As shown, a rectangular honeycomb core 1 is placed horizontally, clamped between a right side plate 2 and a left side plate 4. Positioning grooves 8 are formed on the opposing clamping surfaces of the right side plate 2 and the left side plate 4, and evenly distributed circular holes 7 are formed on the panel of the positioning grooves 8. The rectangular honeycomb core 1 is divided using a wire cutting wire 3 of a wire cutting machine. The clamping and positioning principle of the positioning side plates is as follows... Figure 4As shown, the cuboid honeycomb core 1 contacts the bottom positioning surface 5 and the side positioning surface 6, and the right side plate 2 and the left side plate 4 eliminate the twisting deformation of the cuboid honeycomb core 1 during the wire cutting process. Then, the cuboid honeycomb core 1 is reliably positioned by spot welding the cuboid honeycomb core 1 and the round holes 7 on each side plate with straps.

[0058] It should be noted that the reliable positioning of the cuboid honeycomb core 1 by spot welding the straps to the circular holes 7 on each side plate involves inserting the straps into the circular holes 7 (without extending them out from the other circular hole), and then spot welding the cuboid honeycomb core 1 and the circular holes 7 to connect the straps, the cuboid honeycomb core 1, and the circular holes 7 into a single unit; after cutting, they are then separated. This embodiment solves the problem of difficulty in threading the wire cutting wire 3 when using bow-shaped clamps for positioning the cuboid honeycomb core 1 by using straps to spot weld the cuboid honeycomb core 1 to the circular holes 7 on each side plate. It also solves the problem of poor processing accuracy caused by deformation of the cuboid honeycomb core 1 due to stress release during wire cutting.

[0059] In this embodiment, the rectangular honeycomb core 1 is reliably positioned by spot welding the binding tape to the circular holes 7 on each side plate. This positioning is not only achieved in the height direction, but also in the thickness and length directions by combining the positioning grooves on the left and right side plates. Because varying degrees of torsional deformation occur during the honeycomb welding process, making it difficult to determine the wire cutting position, this method not only achieves positioning but also reduces the deformation of the honeycomb core, ensuring the accuracy of the theoretical cutting position of the honeycomb core.

[0060] S300: The rectangular honeycomb core is divided into two trapezoidal honeycomb cores of the same size using wire cutting technology.

[0061] S400. The segmented trapezoidal honeycomb core is positioned using the support strips on the base plate. The two positioned trapezoidal honeycomb cores are clamped between the base plate and the inclined cover plate and fixed with screws.

[0062] Next, the two trapezoidal honeycomb cores are welded together, using a welding fixture such as... Figure 5 As shown, the positioning principle of the trapezoidal honeycomb core is as follows: Figure 6 As shown. The two cut trapezoidal honeycomb cores are inserted into the hexagonal prism-shaped support strip 12, respectively. Figure 6 The image shows four rows of support bars 12 arranged in the middle of the base plate 9, and symmetrically arranged on the left and right sides of the middle. One side of the core cell of one trapezoidal honeycomb core is inserted into the two rows of support bars 12 on the left, and one side of the core cell of another trapezoidal honeycomb core is inserted into the two rows of support bars 12 on the right, thereby completing the horizontal positioning of the two trapezoidal honeycomb cores and ensuring the strength of the weld during the resistance spot welding process.

[0063] Then, the inclined cover plate 10, the base plate 9, and the screw 11 are used for clamping and positioning to complete the positioning of the two trapezoidal honeycomb cores in the height direction, thus solving the problems of step difference and flatness difference during the welding process.

[0064] S500: Use a graduated hook resistance spot welding gun to spot weld two trapezoidal honeycomb cores together to form a whole wedge-shaped honeycomb core.

[0065] S600, The formed wedge-shaped honeycomb core is subjected to holding machine processing to obtain a high-height hyperboloid wedge-shaped honeycomb core of the target size.

[0066] Furthermore, during the wire cutting process, the long side and end of the right side plate are used as the machining reference for wire cutting.

[0067] See appendix Figure 3 - Appendix Figure 7 This invention provides an apparatus for manufacturing a high-height hyperboloid wedge-shaped honeycomb core. The above-described method for manufacturing a high-height hyperboloid wedge-shaped honeycomb core can utilize the apparatus to manufacture the high-height hyperboloid wedge-shaped honeycomb core. The apparatus for manufacturing a high-height hyperboloid wedge-shaped honeycomb core includes: a positioning side plate, a wire cutting device, a welding fixture, and an electric welding device.

[0068] like Figure 3 , Figure 4 As shown, the positioning side plate includes a left side plate 4 and a right side plate 2. Both the left side plate 4 and the right side plate 2 are provided with positioning grooves 8 and round holes 7 for positioning and fixing the cuboid honeycomb core and reducing the deformation of the honeycomb core. The positioning grooves 8 are set on the opposite clamping surfaces of the left side plate 4 and the right side plate 2, and the positioning grooves 8 have bottom positioning surfaces 5 and side positioning surfaces 6 for accurately clamping and positioning the cuboid honeycomb core 1. The round holes 7 are used to fix the cuboid honeycomb core 1 by spot welding with straps to prevent deformation caused by the release of internal stress during the cutting process.

[0069] Wire cutting equipment is used to divide a rectangular honeycomb core 1 into two trapezoidal honeycomb cores of the same size.

[0070] like Figure 5 , Figure 6As shown, the welding fixture includes a slanted cover plate 10, a base plate 9, and screws 11. Multiple rows of support bars 12 are symmetrically arranged in the middle of the base plate. These support bars 12 help position the two trapezoidal honeycomb cores, ensuring accurate positioning of the honeycomb cores during the welding process. In this embodiment, there are two sets of slanted cover plates 10. The trapezoidal honeycomb cores embedded on the support bars 12 are clamped between the slanted cover plates 10 and the base plate 9 via screws 11, ensuring accurate positioning in the height direction and reducing step differences and flatness issues caused by welding. Furthermore, a gap is left between the two sets of slanted cover plates 10, located above the welding positions of the two trapezoidal honeycomb cores.

[0071] like Figure 7 As shown, the welding equipment is equipped with a graduated hook-shaped resistance spot welding gun. This graduated hook-shaped resistance spot welding gun can extend through the gap between the two sets of inclined cover plates 10 to perform spot welding operations on the two trapezoidal honeycomb cores. The design of this graduated hook-shaped resistance spot welding gun allows it to accurately reach the welding point, while the graduated design helps the operator to more precisely control the welding position, ensuring uniform distribution and strength of the weld points.

[0072] Preferably, the support strip 12 is hexagonal prism in shape. The height of each support strip 12 is not higher than the height of the corresponding honeycomb cell of the installed trapezoidal honeycomb core.

[0073] Preferably, the number of round holes 7 is multiple sets, evenly distributed along the plate surface where the positioning groove 8 is located.

[0074] Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this application is defined by the appended claims rather than the foregoing description, and all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within this application.
